Electroencephalograph tester SEEG 100E

signalEEGautomatic

Overview
The SEEG 100E is a dedicated EEG performance tester for medical device manufacturers, test laboratories and clinical engineering teams. It supports IEC 80601-2-26:2019 compliance testing, provides precise low-amplitude signal generation down to 1µV, and integrates a 620kΩ/4.7nF standard output impedance circuit for realistic EEG source simulation.

Functions

• Output precision: generation of signals from µV range with DAC resolution 0.5µV for accurate amplitude control.
• 9-channel automatic switching: individual channel performance testing with selectable output lead (Ch1–Ch9; Ch10–Ch22 shorted).
• EEG database playback: reproduces clinical or user-defined waveforms (PhysioNet EDF, TXT, Binary and similar formats) for verification of processing chains and algorithms.
• IEC test assistant software: guided procedures to perform IEC 80601-2-26 performance tests, reducing setup time and operator steps.
• SDK for automation: software development kit to integrate and automate test sequences within customer test environments.

Highlights

• Reproducible playback of clinically recorded or custom waveforms to validate device signal handling.
• Wide signal types and ranges: sine, triangle, square, pulses and hysteresis with fine frequency and amplitude steps.
• Built-in output impedance test circuit (620kΩ/4.7nF) and selectable noise injection for realistic test conditions.
